A method of conception where by one lesbian performs fellatio on a man, swishes his load around in her mouth, and spits it into her partner's vagina in hopes of causing a pregnancy.
Those two dykes wanted to have a baby, so I met them at the Holiday Inn for a napa valley conception.
Obviously semen but more specifically semen used as a lubricant after the performance of a creampie. In most cases, the person providing the semen will be the conception balm user at the time of second sexual encounter. If someone else is using your conception balm, it is simply sloppy seconds.
The second time is the best, especially when I leave behind some conception balm.
Person one: Someone threw up in my asshole and I had this really ugly kid; it was like an Andrew Brydon Conception
Person two: Wanna read slash?
Person one: *suicide nades*
